when i work on this modified TYP of TOPO France v4 [Only registered and activated users can see links. ] i get wrong display informations about auto routing polylines in the "Visualisation" windows; it's look like it read the line that is under in the "List of Polylines". I'm not sure if it is a bug...
If i was not clear i apologise for my poor english, so i joint this photo to help
Have a nice week-end
